TO ALL WI'IOM IT MAY CONCERN:

Be it known that I, WILLIAM STONE, of Hollidaysburg, in the county ofBlair, and State of Pennsylvania, have invented a new and usefulImprovement" in Grease-Box for the Axles of RailroadCars; and I (lohereby declare that the following is a full, clear, and exactdescription thereof', which will enable others skilled in the art tomake and use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure 1 is a verticalscc'tionotl my improved grease-box for railroadcar axles.

Figure 2, a front view of the same.

Similar letters of reference indicato like parts.

This invention relates to an improvement in railroad car-axle boxes, andconsists in a sliding lid with lugs cast on the box, to prevent the lidfrom coming out, in connection with a projection cast on the inside ofthc lid, for the same purpose, thereby doing away with screws or belts;and also a projection cast on the top of the box which thelid fits upon,to prevent dirtand dust from entering the box, forming a simple andconvenient arrangement for opening and closing the box, as requiredL Arepresents the box, made of cast iron, and connected with the truck of arailroad-car, as a bearing for the axle, in the usual way. The frontside of the box is made vsloping and partl'y'open, for introducing thetallow or lubricating material, with lugs a a on each side of thesloping part, forming grooves, in which is fitted a lid, B, to slide upand down, for opening and ,closing the box. 'lhe upper side of the lidhas a hooked head, b, which catches on a sharp projection, c, cast onthe top of the box on the front side or edge, by which the lid issupported, and which eiectually closes the upper side of the frontopening to keep out the dust. n the under side of the lid is a smallsharp-cornered projection or shoulder, e, facing upwards, which tapersoi` to nothing downwards, so that the lid can slide down in its placeeasily to close the opening in the front side of the box, but cannotslip or jar out upwards on account of the shoulder c that catchesagainst the sharp edge of a projecting side, d, forming the upper partof the opening in the sloping front of the box.

The lid is thus heldin place over the opening by its own gravity, and,in order to allow `it to be removed easily, the grooves formed by thelugs a a are made wider at the upper part to allow the lid to be liftedenough to let the shoulder e clear the projecting side d, when it isdrawn upwards to open the box for introducing grease into the box forlubrication.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The sliding lid B, with the shoulder-proj e'ction eon the under side, and the hooked head b, in combination with the lugs aa on the sides, and the projection c on the top of the box A, with itssloping side d, arranged and operating' substantially as hereindescribed.

WILLIAM STONE.
